K FREMONT N. JAYNES, OF'MINNEAPOLIS, MINNESOTA. ENVE LOP-SEALING MACHINE.

' To all whom it natty concern:

Be it known that I, FREMONT N. J AYNES, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Envelop- Sealing Machines; and I'do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a simple, cheap, and efiicient machine for sealing envelops; and to this end it consists in the novel devices and combinations of devices hereinafter described, and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts through out the several views.

Referring to the drawings, Figure 1 is a plan view with some parts broken away, showing the improved sealing-machine. Fig. 2 is a side elevation of the same, and Fig. 3 is a vertical section taken on the line a 00 of Fig. 1.

The envelops z preparatory to sealing are placed upon a feed board or table 1, that is adapted to be secured when desired to a desk, table, or other support by any means. (Not shown.) Rigidly secured to the side edges of the feed-board 1 and projecting beyond the rear edge thereof is a pair of verticallydisposed bearing-plates 2, in which are journaled cooperating rollers 3, 4, and 5, which rollers are either made of rubber or faced with rubber. The intermediate roller 3 is relatively large, and its shaft 3 works through suitable slots 2 in the bearingplates 2 and is provided at one end with an operating-crank 6., The slots 2 permit the roller 3 to move slightly toward and from the rollers 4 and 5. U -shaped springs 7, attached at one end to the bearingplates 2 and pressing at their other ends against the shaft 3, keep the feed-roller 3 pressed into close engagement with the roll- The roller 4 is preferably a wooden roller provided with external rubber rings 4 Extending transversely over the feedboard 1, close to theupper surface thereof and close to the rollers 4 and 3, is a perforated water-tube 8, that is journaled in the bearing-plates 2 and is provided with an external covering of cloth or other absorbent porous Specification of Letters Patent.

material, (indicated at 9.) At one end this water-tube'8 is closed, and at its other end it is provided with a radially or eccentrically extended water-containing reservoir or bottle 10, that is provided with a detachable stopper 11. When the reservoir 10 is turned upward, as shown by full lines in the drawings, the water will be fed therefrom into the perforated tube 8; but when the said reser voir is turned downward, as shown by dotted lines in Fig. 3, the water will run from the said tube back into the saidreservoir. By turning the reservoir up and then again down at the proper intervals of time the cloth tube-covering 9 may be kept dampened to the desired extent for properly moistening the gummed flaps of the envelope.

Supported by the bearing-plates 2 and extending at an angle of about forty-five degrees and positioned to properly direct the envelops downward between the rollers 3 and 5 is a so-called deflecting-leaf, which, as shown, is niade up of a transverse rod 12 and a rod 13, which latter is bent to form the extended portion of the defiectingleaf, is wound around the shaft 12 at several different points, and at its ends is attached to said supporting-plates 2.

xtending transversely of the machine, above the feed-roller 3 and at the rear of the upper press-roller 4, is a light rod 14, the ends of which are attached to the bearing-plates 2. On this rod 14is pivoted or fulcrumed a skeleton flappressing lever, preferably formed from a single piece of wire bent to form a bail 15, having rearwardly-extending arms 15, and having the intermediate portion of itslaterally-spaced arms coiled around the said rod 14. The transverely-extended forward portion of the bail 15 directly overlies the perforated moistening-tube 8, while the rearwardly-extended arms 15 stand in position to be engaged by the projected edge of the envelop, which is in the position or approximately in the position shown by dotted lines in Fig. 3.

The relative arrangement of the parts above described will more fully appear in the following description of the operation. The envelops are laid on the feed-board 1 approximately in the position indicated by full lines in Figs. 1 and 2, and at this time the flappressing lever 15 15 stands approximately in the position indicated by dotted lines in Fig. 2. The envelop is pushed rearward until its sealed edge is caught between the rollers 3 and 4, said rollers being then driven in the direction of the arrows marked on Fig. 3. As the envelop is drawn farther rearward by the rollers 3 and 4 the gummed edge of its flap will be brought against the absorbent covering 9 of the water-tube 8. At a time considerably before the envelop is moved to the position indicated by dotted lines in Fig. 2 and at a time after its gummed. flap has been carried against the moistening-tube and under the transverse portion of the lever-bail 15 the rear edge of the envelop strikes the arms 15'" and raises the same, thereby pressing the said bail 15 down, and thereby causing the latter to hold the flap of the envelop in close engagement with the absorbent covering of the said water-tube. This insures proper moistening of the gummed edge of the envelop-flap. As the rear edge of the envelop is passed to the rear peripheral portion of the roller 3 the spring-arms 15 are forced farther upward, but all this time by their downward yielding pressure keep the envelop pressed against the rear peripheral portion of the roller 3, thereby insuring the delivery of the rear edge of the envelop between the rollers 3 and 5, and, furthermore, assisting in starting the envelop between the said two rollers 3 and 5. The skeleton supporting shelf or leaf 12 13, as well as the spring-arms 15 will yield very considerably, so that envelops that vary a great deal in size may be run through this machine and sealed. without readjusting any parts of the machine.- The springs 7, which yieldingly force the feed rollers 3 against the press-rollers 4 and 5, Will yield and permit sufficient lateral movement of said feed-roller to permit the proper passage between the said rollers of envelops that are filled to a greater or less extent.

The machine above described while extremely efficient for the purposes had in view is of very small cost, and, furthermore, is durable, and has no parts that are liable to get out of order. The feed roller or rollers may of course be driven either by hand or any other source of power.

I claim as my invention- 1. In a machine of the kind described, the combination with an intermediate and cooperating upper and lower roller, of a moistening device in position to moisten the gummed flaps of the envelops as they are fed between the intermediate and upper rollers, an inclined shelf arranged to receive the envelops as they are delivered from between the intermediate and upper rollers, and to direct the same between the intermediate and lower rollers, and a lever arranged to be engaged by the envelops delivered to said shelf, said lever having a part for pressing the gummed flaps of the envelops against said moistening device, substantially as described.

2. In a machine of the kind described, the combination, with an intermediate and cooperating upper and lower roller, of a moistening device arranged to act upon the gummed flaps of the envelops as they are fed between the intermediate and upper rollers, an 1n, clined shelf arranged to receive the envelops delivered from between the intermediate and upper roller and to direct the same'between the intermediate and lower rollers, and a spring device arranged to act upon the envelops delivered to said shelf to hold the envelops pressed against said intermediate roller and to assist in delivering the envelops between said intermediate and lower rollers, substantially as described.

3. The combination with three cooperating feed-rollers and a moistening device extending parallel therewith in front thereof, of an inclined deflecting-shelf located at the rear of said feed-rollers, for directing the envelops between the intermediate and lower rollers, and a lever intermediately pivoted and overlying said deflecting-shelf and said moistenlng device, and arranged to force the gummed flaps of the envelops onto said moisten ng device, when engaged by an envelop WlllGh has been delivered onto said deflecting-shelf, substantially as described.
